I saw on Fox news a commentator stated that periodically, Israel needs to clean out Gaza and kill the terrorists. He made a great analogy: it is like mowing your lawn.You have to mow the lawn when the grass gets too high. Isreael is now mowing the lawn of terrorists. They will have to mow again in the future when the terrorist count gets too high.
They also have the option of treating the lawn.. so the grass doesn’t come back.
